often obscure, so that a number of the genera described by

We must refer to the Introduction of Wight and Arnott'
for full details regarding the illustrious series of botanists*,
commencing with Konig and ending with Wallich, who in-
vestigated with so much success the-botany of continental
India. The volumes of the ' Asiatic Researches/ and of most
of the systematic works of the end of the last and beginning
of the present century, afford ample proof of the value of
their labours; but none of them brought their materials to-
gether in the form of a flora, except Roxburgh, whose f Flora
Indica* however remained in manuscript for some years after
his death, in 1815. Two-editions of it have been published
since that period; one, which is incomplete, was edited by
Drs. Carey and Wallich; it extends to the end of Pentandria
Monogynm, but contains in any additional plants not con-
tained in Roxburgh's manuscript, and requires therefore oc-
casionally to be quoted; the other, which is an exact reprint
of the manuscript as left by its author/ is in three volumes,
and was published in 1832.
Besides editing this portion of the f Flora Indica' of t)r.
Roxburgh, Dr. Wallich commenced, in India, an illustrated
work on Nipal plants, -which was the first specimen of iithor
graphy ever produced in that country; and after his return
to England, he published a series of 296 plates of plants in
the' Plantae Asiaticse Rariores/ a work which, with the equally
valuable Coromandel plants'of Dr. Roxburgh, in three folio
yolumes, with three'hundred coloured plates, forms the prin-
cipal contribution of the Indian Government to the illustwu
tion of botanical science.

botanically till it was visited by Jack, whose descriptions of
